Executive Summary

A critical SQL Injection vulnerability (CVE-2026-32714) has been identified in the `KeyCache` class of the `scitokens` package, affecting solo developers and small teams. This vulnerability allows attackers to execute arbitrary SQL commands against the local SQLite database, posing a significant risk of data manipulation and potential Remote Code Execution (RCE). Immediate action is required to mitigate this risk.

Immediate Action

  • Immediately review and update your `scitokens` package to a safe version.
  • Replace all instances of string formatting in SQL queries with parameterized queries.
  • Isolate any affected services to limit exposure until a patch is applied.
  • Conduct a security audit to assess any potential data breaches or unauthorized access.
  • Monitor your application logs for unusual activity that may indicate exploitation attempts.
  • Refer to vendor advisories for updates and further guidance.

Affected Versions

  • scitokens@<=X.Y.Z vulnerable; upgrade to X.Y.Z+ (exact version TBD)

Resolution Guide

To resolve this vulnerability, follow these steps:

pip install --upgrade scitokens

Ensure you replace vulnerable SQL query patterns with parameterized queries. For example:

curs.execute("DELETE FROM keycache WHERE issuer = ? AND key_id = ?", (issuer, key_id))

Additionally, consider hardening your configuration by disabling any unnecessary database extensions that could be exploited.

Detection & Verification

To check if you are vulnerable, run the following command to verify your `scitokens` version:

pip show scitokens

To verify the fix, ensure your application no longer uses string formatting for SQL queries and confirm the installation of the updated package:

pip show scitokens

Risk and Impact

Exploitation of this vulnerability could allow an attacker to modify or delete cache entries, leading to data loss or corruption. In some configurations, it may also facilitate Remote Code Execution, significantly increasing the attack surface and potential damage to your application and infrastructure.
